Irish mobile operator O2 Ireland posted revenues of EUR237 million in the three months to 30 June, up 4.5% year-on-year and 6.5% higher than in 1Q-2007, although the company’s subscriber base dipped from 1.6325 million in March to 1.6315 million by end-June. Revenue growth was driven by a rise in average revenue per user (ARPU), with the blended total rising 5.6% from EUR44.2 in the first quarter to EUR46.70. Pre-pay ARPU was up 7% quarter-on-quarter at EUR30, while contract ARPU climbed 2.2% to EUR83.80. Average monthly minutes of use (MOU) rose 5% year-on-year to 249. Paul Whelan, chief finance officer with O2 Ireland, said: ‘ARPU growth was particularly driven by the increase in our post-pay customer base, which grew by 13.5% when compared to the same period last year.’ Whelan added that in general he was satisfied with the figures, and noted that early indications suggested O2’s mobile broadband service, launched a month ago, was ‘exceeding expectations’.
